VALQUALON Gasket 7020

Specification of VALQUALON Gasket 7020

VALQUAFLON 7020

In order to improve the cold flow (creep phenomenon),

which is a drawback in PTFE, these gaskets are shaped by

means of a special manufacturing process where

inorganic filler material is compounded. Provided with

heat resistance, chemicals resistance, and anti-cold flow

property, they are best suited for lines handling various

chemicals (high concentrated hot sulfuric acid, hot nitric

acid, etc.). However, they are not suited for high

concentrated alkali such as sodium hydroxide and

hydrofluoric acid.
